I have an Acer Swift 1. It too conked out with black screen and unable to repower. I found an easy solution for my case. 1. Check the bottom of your laptop and look with a magnifying glass if necessary for a very small symbol of a battery. I don’t know which Acer models will have this setup. 2. Above that symbol you will see a tiny hole. 3. Put a pin or needle through the hole and press down for five seconds. 4. Wait for several minutes then power up. It worked for me. 5. I found this solution on a web site that I cannot now find! 6. I cannot find any reference to this procedure nor indeed to the symbol and pinhole in Acer manuals. I believe this approach removes static: you may have to repeat it once or twice to clear the machine.
